A 40-sided polygon has 40 sides. Count again, to be sure.
Number of sides: 360/40 equals 9 sides
The sum of the exterior angles of a regular polygon equal 360° .If one such angle measures 40° then the polygon has 360/40 = 9 sides.
A tetracontagon.
If it's a regular polygon then it will have 40 sides
40 sides
if the exterior angle is 40 degrees the interior angle of the polygon is 180- 40 = 140 degrees. The equation for sides N is interior angle = 180 x (N-2)/N; solving you find N = 9 sides
9
40 sides
40 sides
It is: 360/40 = 9 sides
A regular polygon with an exterior angle of40O is a nonagon, and has 9 sides.
